This is a weird one, I think?

I have Emby set up in my home with my HDHomeRun for live TV.  Everything works beautifully.

My sister lives in an area where an antenna doesn't get great signal (something-something-mountain).  We have a site-to-site VPN between our houses on our Synology routers (because I'm her tech support), so I decided to set her up an Emby server and connect my HDHomeRun.

I have memories years ago of it working (we know memory is fuzzy, so I accept that the statement isn't trusted).  I was recently told she tried to watch local channels and it just spun.

I finally had a chance to get to her place and look at things.  And, alas, it just spins when I tune into a HDHomeRun channel.

My setup (which works):

ProxMox 9.1.9 server with a Debian  13.4 VM
Passthru NVIDIA 3050
Emby Server 4.9.3.0 running via Docker
Emby Premiere
HDHomeRun CONNECT 4K

My sister's setup 

ProxMox 9.1.9 server with a Debian  13.4 VM
Passthru NVIDIA 3050
Emby Server 4.9.3.0 running via Docker
Emby Premiere
Attempt to connect to my HDHomeRun through a site-to-site VPN (failed)

I'm in her house and I can connect to my home Emby using http://<myLANIP>:8096 from my laptop and I can successfully play my HDHomeRun channels.

However, when I try to play the same channel from her Emby server, it spins and fails.  My HDHomeRun status page shows a tuner connected to that channel.

I thought there might have been some corrupt configuration in her setup, so I spun up a fresh Emby Docker container with the same result.

Initially, all attempts to play were on her Roku TV, but I have since gone to testing things on my laptop with the same results.

Here's what I've tested:

  1. Browser on my network
    1. HDHomeRun through my Emby server works
    2. HDHomeRun through my sister's Emby server does not work
    3. Playing channels from my HDHomeRUn via Media Player Classic works
    4. Playing .m3u channels (ersatztv) from my home network to my sister's Emby server works
  2. Browser on my sister's network
    1. HDHomeRun through my Emby server works
    2. HDHomeRun through my sister's Emby server does not work
    3. Playing channels from my HDHomeRun via Media Player Classic works (same laptop as above)
    4. Playing .m3u channels (ersatztv) from my home network to my sister's Emby server works

Do you have any ideas why HDHomeRun isn't working with only my sister's Emby?

You got a 502.

An HTTP 502 (Bad Gateway) error means an intermediary server (like a proxy, load balancer, or CDN) received an invalid response from the origin/upstream server. Your request reached the gateway, but the gateway couldn't connect to the actual website server.

Thanks @speechles!  That was super helpful (and I don't know why I didn't fully notice that).

New info:

  • From my sister's network's Emby Docker container, I can successfully wget http://<hdhomerunip> (port 80 implied)
  • From my sister's network's Emby Docker container, I CANNOT wget http://<hdhomerunip>:5004 (different network, crossing vpn)
  • Form my home network's Emby Docker container, I CAN successfully wget http://<hdhomerunip>:5004 (same network)
  • From my sister's Docker Host VM, I can successfully wget http://<hdhomerunip>:5004
  • If I change the Emby Docker container to use "network_mode=host", I CAN successfully wget http://<hdhomerunip>:5004

That's leading me to believe either something is set up awry in the Emby Docker Container related to firewall, or there's something funky set up in Docker related to similar.  Basically, Docker.

For now, I'll set her stuff up in host network mode and hope it doesn't affect any other containers on her VM, until I can figure out if it's a Docker setting or what.

Thanks again for your help!

No it's actually the HDHR throwing the error. Can you try rebooting the tuner and see if that helps?

Rebooting the tuner didn't do anything.

As I said earlier, it looks like it's either some firewall-type configuration in Docker or a configuration of the Container.

When I set the Network Mode to "host" (which appears to be the default setting for DNLA and Wake on Lan settings, according to the comments in the Docker Compose [e.g. two features I don't use])., everything works.  When I remove the Network Mode configuration and just use port mapping (which just maps into the container, not outwards), it doesn't work.

I've decided to just run the container with Network Mode as host until I either figure out what's going odd with it, or it causes another conflict.  I doubt the conflict will happen, since I limit the services on the Emby VM.

Yea this is the simplest thing to do. When you use bridge mode it will probably require many other things to be configured as well.

That's my plan.

I think there's something odd with Docker networking (I'm now experiencing an oddity in another container on a different machine) that's well outside the scope of this forum.  If I ever figure it out, I'll post a follow-up.  Until then, we can consider this closed.

I believe the HDHR are set for a limited number of hops, getting to your sisters place probably exceeds that.

I think that can be changed check out the HDHR forums...
